Show HN: MailCat – Email service for AI agents (open-source) (github.com)

MailCat has launched an open-source email service designed specifically for AI agents, allowing them to bypass common verification hurdles encountered during automated workflows. With a straightforward REST API, MailCat enables users to create mailboxes in an instant, extract verification codes automatically, and manage emails seamlessly—all without requiring a signup process. This innovation addresses the often cumbersome email verification step that AI systems face, enhancing their ability to autonomously interact with online services. Significantly, MailCat is positioned to empower AI agents in a variety of tasks including automated signups, CI/CD pipeline testing, and alert monitoring. Its privacy-focused features ensure that emails are automatically deleted after one hour, while self-hosting capabilities on platforms like Cloudflare provide flexibility for deployment. The tool supports multiple programming languages and frameworks, making it accessible for developers looking to integrate email functionalities into their AI workflows. With its MIT license and complete transparency, MailCat not only simplifies email interactions for AI but also fosters community collaboration in the rapidly evolving AI/ML landscape.
